The correct answer is (a) Landfill

Explanation: Solidification, incineration, chemical oxidation, aerobic oxidation or anaerobic fermentation are the combination methods that can be used to process the hazardous wastes, designed to treat or dispose of the hazardous wastes safely. But landfill is also a method used to dispose of the hazardous waste but it is not a combination method.
